I download the CTA 7.5 trial version but doesn't work. The VM start and I can use the setup tool but I can't open the management GUI (ping work).
I'm sorry to hear you're having problems and I'm not sure why. I'm looking into it with the person who built the trial version and will get back to you as quickly as I can.
You can ping the VM, and you can ping from the VM, correct? You can ping to/from the machine you’re running the browser on? Does the GUI come up in the browser? What error message do you get?
